DESCRIPTION

Local users on a system may be able to exploit security flaws in
sendfiled to obtain root privileges.


SOLUTION (See also: UPDATING VIA APT-GET)

Upgrade to a fixed version of sendfile. sendfile version 2.1-24
corrects the problem. For your convenience, you may upgrade to the
sendfile_2.1-24 package.


WORKAROUND

sendfile may not be a vital system utility in every installation.  If
you prefer, you can remove rather than upgrade sendfile.  To remove
it, use this command:

  dpkg --remove sendfile


UPDATING VIA APT-GET

 1. Ensure that your /etc/apt/sources.list file has a URI for Progeny's
    update repository:

        deb http://archive.progeny.com/progeny updates/newton/

 2. Update your cache of available packages for apt(8).

    Example:

        # apt-get update

 3. Using apt(8), install the new package. apt(8) will download the
    update, verify its integrity with md5, and then install the
    package on your system with dpkg(8).

    Example:

        # apt-get install sendfile


UPDATING VIA DPKG

 1. Using your preferred FTP/HTTP client to retrieve the following
    updated files from Progeny's update archive at:

    http://archive.progeny.com/progeny/updates/newton/

    MD5 Checksum                     Filename
    -------------------------------- -------------------------------------
    903eef59cc9253d6d732326eafe9c307 sendfile_2.1-24_i386.deb

    Example:

        # wget \
        http://archive.progeny.com/progeny/updates/newton/sendfile_2.1-24_i386.deb

 2. Use the md5sum command on the retrieved files to verify that they
    match the md5sum provided in this advisory:

    Example:

        # md5sum sendfile_2.1-24_i386.deb

 3. Then install the replacement package(s) using the dpkg command.

    Example:

        # dpkg --install sendfile_2.1-24_i386.deb
